Measurable Success can be measured by the number of applications, interviews and job offersSection 16 Vector Functions We first saw vector functions back when we were looking at the Equation of LinesIn that section we talked about them because we wrote down the equation of a line in \({\mathbb{R}^3}\) in terms of a vector function (sometimes called a vectorvalued function)In this section we want to look a little closer at them and we also want to look at some vector functionsDefinition In the case of a space curve, the radius of curvature is the length of the curvature vector In the case of a plane curve, then R is the absolute value of ≡ =, where s is the arc length from a fixed point on the curve, φ is the tangential angle and κ is the curvature Formula In 2D If the curve is given in Cartesian coordinates as y(x), then the radius of curvature is

Y=a(1+r)^t examples-The characteristic equation is r2 5 r 4 = (r 1)(r 4) = 0, the roots of the polynomial are r = −1 and −4 The general solution is then y = C1 e −t C 2 e −4t Suppose there are initial conditions y(0) = 1, y′(0) = −7 A unique particular solution can be found by solving for C1 and C2 using the initial conditions First weIn this section we solve linear first order differential equations, ie differential equations in the form y' p(t) y = g(t) We give an in depth overview of the process used to solve this type of differential equation as well as a derivation of the formula needed for the integrating factor used in the solution process

At any point along the path, the (small) tangent vector ${\bf r}'\,\Delta t$ gives an approximation to its motion over a short time $\Delta t$, so the work done during that time is approximately ${\bf F}\cdot{\bf r}'\,\Delta t$;= 1 r Subtracting 1, you get that the rate is just over 003 or 3/10 of 1% The function that would model your growth is y = 484(1003)^t To do #2, find out how many years each year is after 1980, and plug those numbers in for "t" For example, to find 1985, you'd take 484(1003)^5 To do #3, "double" the original population would be 968 million peopleFor t and r must be the same Example of Exponential Growth The 00 census found that a US Population of about 281 million with an estimated growth rate of 07% Q = Q0 x (1 r)t 4/1/10 2 Forms of the Exponential
